Patch 5.4 is a Complete Joke
I have a lot to say about these stupid upcoming changes so bare with me .
Here is unofficial patch 5.4 draft http://lol.arcana-gaming.com/en/Article/1920/league-of-legends-unofficial-5-4-pbe-patch-notes
Veigar --- Why are we nerfing Veigar in a first place ? Pick one of these

Delay on stun . This reminds me the time Riot reworked Fiddle's fear to make people run away effectively destroying his combo . This will certainly kill Veigar's laning phase and late game utility by destroying his E>W>Q>R . This is clearly huge mistake by Riot and I expect them to admit it like they did with Fiddle .
Comet
Well why bother with lowering cooldown on W if we can't land it anymore ? It was difficult to land it with instant stun let alone with a 0.75 second delay .
**Q will be a skill shoot **
I have no idea what RIot was thinking here . Veigar in lane can easily be harassed because he has to use his Q to farm AP therefor he can't fight back . This change will let enemy champions safely stand behind minion waves for any retaliation and farming with Q won't be nearly efficient . Further if enemy champion is behind minion wave they will be safe from Veigar's full combo .
**Ultimate **
Less damage for less mana . Do to Veigars passive his mana pull is not really a problem if you run some mana regen runes . Another Nerf.
Riot went too far with Veigar . It will kill the champion .

Zilean-- Loosing his global was a huge nerf reducing his team exp from 40% to 8-16%.
SO RIOT said this is a buff! Lets look at this buff shall we ?
Q will work like throwing Granade
It prioretizes champions but keep in mind that these skills are hard to land because of delay . This is not helping zilean with harass especially since this is HE'S ONLY DAMAGE SOURCE .
** No more CD reduction for ulti**
Wait this is a buff to Zilean? What ? WTF is this
Slow is 99% at max level
Ok thats nice but whos gona max out E over Bomb ? Its a buff but its gona take effect so late in game that it won't matter especially since its not even a stun!
**Ultimate **
So at max rank ultimate is 60 seconds now . This is at level 16 so this is a bit late for solo Q don't you think?
Overall I see this game destroying Zilean's early to mid game . How are you buffing champion by beating him to the ground .

Sona
Some people will debate on how Sona doing right now but in my opinion she is struggling in higher elo .
Notable riot increases her movement speed by 5 but i think the issues is inside her kit and not base stats .
I would like to see her kit having some strong buff for AD carry but currently she has to stay too close and buffs are too short .

Also I can't find anything about jungle changes . Please post link here if you get any info as its very important to a Tank main .
